curing the tape to the edge portion of -the garment. The tape is most commonly secured by sewing and less commonly by the use of adhe- Sives. Whensecured by means of adhesives, the wunion effected ,is not strong, /is subject to tearing away or'stripping accentuated by repeatedpulling dueto slideroperation and is generally unsightly., f `Z t `'Ihepriine object'of my'present invention relates to' the` 'making 'of Slide fasteners designed for'adhesive attachment to the article to which `it is to belaplplied,jemb`odying `the following features of structure and advantage:

`1. Thefs'tririger tape is hdoublefply, the two plies being coatedpnltheir' interior contiguous faces with the adh'sfive''Y 'I'he `tWO plies form open wings which are adaptedto receive therebetween, 4' H 'my chmen'tto he opposite faces of, en 'edgegpo on Qrtnearticleffer which' it is to p` able fastener. rWhen attached,

To the accomplishment of the foregoing and "'awaybecomes impossible,

such other objects as may hereinafter appear,

attaching the fastener elements thereto;

Fig.v 3 is a View of the same also taken in crosssection and shown on an enlarged scale and showing the manner of attaching the Stringer to the edge portion of a garment or the like;

Fig. 4 is a view corresponding to that of Fig. 2 and showing the modification; and

Fig. 5 is a View corresponding to Fig. 3 of said modification.

Referring now more in detail to the drawing, the Slide fastener Stringer of my presentv invention comprises a double ply tape T having a beaded edge B and slide fastener elements f, f attached along the beaded edge, the two plies p and p2 of the tape T each being coated on their -interior contiguousfaces f and f2 with the ad- The adhesive coatings The tape T is -a textile fabric formed by folding a fabric sheet into the configuration best Shown in Fig. 2A of the drawing, thus producing the folded ed-ge IIJ and the two plies p and p2. In the form of the invention shown in Figs. 1 to 3, two cords I2 and t4 are sewn by a line of stitching IB to the folded edge l0 to form the beaded edge, and the fastening' elements f, f are clamped on to the thus reinforced or beaded tape edge to produce the resulting Structure shown in Fig. 3. The adhesive coating is applied t0 one side of the textile fabric sheet `preferably before the same is folded, and the adhesive employed is a thermo-responsive adhesive, that is` to Say, one that is either thermoplastic or thermosetting. In

face of the fabric Sheet is coated with a layer of a thermosetting resin. After vthe coating operamaining areas of the 'tape plies remain free or` unattached and these free areas of the tape lplies form normally dry adhesive coated open wings as shown in Fig. 2 of the drawing. j

The thus constructed tape of Fig. 2 is used for making the stringer of Fig. 3 andkv the said stringer is then handled and may be marketedl for use by the consumer ready for attachment to an edge portion I8 of a garment or other article in the manner depicted in Fig. 3. The normally open wings'of the stringer are thus adapted to receive therebetween the edge portion I8 of a garment and attachment or union is effected by asseoir ready for use by the consumer for attachment to a garment without sewing and without treating either the garment edge or'the tape in any way. By reason of the resulting construction as shown in Figs. 3 and 5, stripping or tearing away of the tape from the garment at the beaded edge is well nigh impossible; the unionis strong and pracy .tically permanent. The edge portion i8 being hot pressing as by means of a hot iron, the laminated arrangement thus` produced. The hotpressing may be eiected either by applying the iron to either side or both sides of the tape plies p' and p2.

In the form ofthe invention shown in Figs. 4

and 5, the tape T' having the plies p3 and-p4 is coated with a thermoplastic resin so that 'the entire face of the sheet fabric is provided with the layer of the thermoplastic resin. In this form of the invention the fabricsheet which forms the tape is folded at around so as to embrace i the beading cord 22. Sewing of' this cord on the tape is dispensed with; the cord 22,- suitably stretched, is instead cemented in place by heating in a die operating in the region, around the cord. Thereby the plies p3 and p4 are not only adhesively united over the area a which encompasses the beaded edge ind the attached slide fastener elements, but the beading cord is secured in position by the adhesive. Fig. 4'shows the resulting tapeas ready for use in-making the stringers. Here again the tape has-free or un-united areas which form normally dry adhesively coated open wings.

r y The tape of Fig. 4 is then used to 'make a stringer as shown in Fig. 5

and as exemplified by Fig'. 1 in which the contiguous faces of the open ply wings are coatedat c3 and c4 with a thermoplasticresin which in coating. As before, this product maythenV be attached to an edge portion ofthe garment-such as the edge portion-24 in a manner similar to that described in connection with Figs. 2 and 3 of the drawing.

'Ihis structure makes possible the use of strips slit from cloth instead of woven tapes. Any suite able cloth provided on one face with the adhesive can be slit to double width of the commonly-used tape, folded, and further used like a woven double ply. The advantages are that such strips, ob-

tained from cloth made on large looms, are lessexpensive than narrow tapes madeon'special looms, and that great lengths or widths of cloth can more easily be. coated with Vadheslyesthan narrow separate strips.' There would be no objection to using such slit' strips because all the rough edges at the fold would be secured against fraying -by the applied coating. In making the tape from either cloth or woven strips, instead of folding a strip of double width. the invention .enables the use of two separate tape strips stuck or'adhered together at one edge.

The slide fastener Stringer of the present invention and the manner of making the same and the advantages thereof will in the main be fully appaxeni'.'froln the above detailed description thereof. A' stringerproduct is produced which is the finished product is a normally dry adhesivev over the remaining areas,

-tape plies forming normally wholly concealed by the attached tape may have an unselvaged or unnnished' edge; the resulting closure is neat Vand sightly. The consumer may attach 'the stringer to the garment by a simplehoil pressingoperation. The preliminary uniting of the tape plies at the area a or a' simplifies the handlingof the tape during stringer manufacture and facilitates the operation of adhesively attaching the same to a garment illustrated in Figs. 3 and 5 of the drawing. The symmetry of the arrangement shown in these figures is the means of producing a well balanced structure.

While I have, shown the invention in the p referred forms, it -will Abe apparent that changes i may be made therein without departing from the spirit of the invention defined in the following claims. l

I claim:

A slide fastener Stringer comprising a double ply tape having a beaded edge and slide fastener elements attached along the beaded edge, the two p liesofthe tape lbeing coated on their interior contiguous faces with an adhesive, the said plies being adhesively united over the areas encompassed by the beaded edge and attached slide fastener elements,` and being free over their remaining areas, the free areas of thev tape plies forming normally .dryadhesively coated` open a wings adapted to receivetherebetween, for adhesive attachment to the opposite faces of, an
